To transform a table of numbers into score and loading plots we use a mathematical technique called projection.
We start with some observations (objects, individuals, molecules, time points, …) and variables (measurements, spectra, facts, …) in a data table.
If we look at just one variable, we can plot the observations on a single scale to visualize them. In this figure we have also reduced the number of observations to one – the yellow dot.
